Product Description:

Released: August 2015

A new high-performance scientific calculator with high-resolution display increasing the amount of information displayed and super-fast calculation speed for high-stakes testing or for performing the most advanced mathematics.

Its new high resolution LCD screen allows more information for applications like spreadsheets and 4X4 matrix calculations. This calculator has a comprehensive set of advanced calculations for integration and differential calculus, along with vector and inequality calculations. For the middle and high school grades, we've incorporated basic spreadsheet functionality, ratio, and statistical functionality, down to ratio calculation and prime factorization.

No matter what the need, this scientific can do it all! Need graphical representation for data generated by the fx-991EX – no problem! Generate a QR code for your problem, and then scan the code to immediately see a graphical representation of your data; within a classroom, students can see their collective data in real time with other students.

  • High-resolution LCD
  • Effective learning for Advanced Mathematics
  • Online Visualization Service Using QR Code
